Brad Sherman introduced articles of impeachment accusing Trump of obstruction of justice and seeking to "use his authority to hinder and cause the termination" of the investigation into former national security adviser Michael Flynn.
"Recent disclosures by Donald Trump Jr. indicate that Trump's campaign was eager to receive assistance from Russia". Impeachment requires majority votes in the House and Senate, both of which are currently controlled by Republicans.
Al Jazeera's Heidi Zhou-Castro, reporting from Washington DC, said Sherman's move was "a protest statement that does formally initiate the process of impeachment, but it's likely to stop right here where it started". Some Democratic leaders have distanced themselves from efforts to impeach Trump, fearing it only would energize the president's supporters.
Sherman acknowledged that his effort faces an uphill struggle, calling Wednesday's announcement "the first step on a very long road".
The president has questioned his own intelligence agencies and whether the Russians actually interfered in the election. "But given the risk posed to the Republic, we should move things forward as quickly as possible".
Green previously said he would be drafting Articles of Impeachment against the president, though the effort may be fruitless.
"Lack of impulse control, accompanied by a refusal to have his staff control his impulses". The FBI and other agencies claim they have proof Russia attempted to meddle with the outcome of the presidential race between Trump and Clinton.
The start of the G20 summit, which runs from Friday to Sunday, was marred by violent protests in Hamburg.
He dismissed the idea that there wasn't widespread support for the "I word", saying, "everybody in the country is talking about impeachment".
Democrats in Congress voiced outrage and insisted the messages showed clear collusion.
He also expressed hope that the filing could shock the White House into better behaviour, seeing "incompetency replaced by care". The impeachment is then tried in the Senate in a proceeding overseen by the chief justice of the Supreme Court.
Sherman is an 11-term Democratic representative, and a member of the House Foreign Relations Committee.
However, in case you are wondering that who will be next 'POTUS', hold your horses. Green's involvement in the measure comes as no surprise.
The detail committee at the Constitutional Convention in 1787 originally listed "treason, bribery and corruption" as grounds for impeachment, but later removed "corruption" before settling on "high crimes and misdemeanors", according to the Heritage Foundation.
